MILK-PAIL COVER AND STRAINER.

SPECIFICATION forming part of Letters Patent No. 739,080, dated September 15, 1903.

Application filed April 14, 1903. Serial No. 152,490. (No model.)

To all whom it may concern:

Be it known that I, EDWARD M. HAYMAKER, a citizen of the United States, residing in Genterview, county ot'Johnson, State of Missouri, have invented certain new and useful Improvements in Milk-Pail Covers and Strainers, of which the following is a specification.

My invention relates particularly tocovers for milk-pails; and my main object is to provide an improved mechanism for straining the milk before admitting the same to the pail.

The invention is fully described in connection with the accompanying drawings, and the novel features are particularly pointe out in the claims.

Figure 1 is a sectionalelevation of my improved straining-oover applied to a milk-pail. Fig. 2 is a partial plan view of the same. Fig. 3 is a separate view of the inner clasp ring, and Fig. 4 is a reduced plan view of the flat filtering-cover.

A represents the top portion of a milk-pail, upon the beaded edge 1 of which the downwardly-flanged rim 2 of the pail-cover 3, with its beaded edge 4, is snugly fitted, thr'ee crimps or depressions 5 in said edge 4 being preferably provided, as indicated in Fig. 2, to facilitate the operations of attaching and detaching the cover. The main portion of this cover 3 is preferably formed, as shown, from a circular disk of sheet metal having a central opening. The rim 6 of the latter is downwardly and outwardly flanged, as indi-' cated, to serve as a filter-clasping nozzle-rim, as hereinafter explained, and the sloping portion adjacent to said nozzle forms a somewhat flattened funnel or funnel-bottom 7, extending to the circular ridge 8, beyond which latter is the reverse slope 9, joining the previously-described downwardly-flanged and headed rim 2, as shown in Fig. 1. The body 10 of the funnel is separately formed and suitably connected to the main cover 3 at or adjacent to the ridge 8.

In connection with the cover 3 I employ a separately-formed settlingreceptacle 11, made from a single piece of sheet metal pressed to shape, as shown, to form a shallow vessel of considerably larger diameter than the-funnel-nozzle 6, having its central bottom portion 12 elevated to receive the milk delivcilitate cleaning.

ered flOlll the funnel-nozzle, and a depressed annular settling chamber or gptter 13. The rim 14 of this settling-receptacle rises above the raised bottom 12, so as to provide for retaining a proper depth of liquid therein to insure the settling of heavy foreign matter into the annular chamber 13, and it is so shaped as to serve, in connection with the outer claspring 15 on the coverhereinafter referred to,the purpose of clamping the circular outer edge of the filtering-cover 16, as indicated. This filtering-cover for the settlingreceptacle, which is provided for the purpose of straining the milk as it overflows from the receptacle into the pail, is a separately-formed and readily-renewable covering in the form of a flexible disk With-a central opening and is preferably made of fibrous material, as cotton batting, held between two layers of cheese-cloth and having an outer diameter somewhat greater than the diameter of the receptacle-rim 14 and a central opening some- ,what smaller than the funnel-nozzle 6, so as to provide overlapping inner and outer edges 17 and 18 for clamping the same respectively between'the outer clasp-ring 15 and the rim 14 of the receptacle and an inner clasp-ring 19 and the nozzle-rim 6. The ring 15 is removably held in concentric position upon the under surface of the cover by a circular series of guide-lugs 20, fixed to the latter, thus permitting of its being easily removed and cleaned. The inner ring 19, as shown in detail in Fig. 3, is a split one formed of springwire to permit of its being readily sprung upon or removed from the nozzle-rim 6 to clasp or release the inner edge 18 of the filtering-cover. The abutting ends 23 of the wire are rounded, as shown in Fig. 3, to fa- The outer edge 17 of the filtering-cover is pressed against the ring 15 by the conically-formed rim Moi the settlingreceptacle when the latter is secured to the cover. The means provided to effect this copnection to the cover preferably consist of a central standard 21, rigidly fixed to. the.
